Using the first direct current generator 101 as motor running, drive the second direct current generator 102 to rotate by the first direct current generator 101 by coaxial connector 103, make the second direct current generator 102 be operated in Generator Status.The electricity that second direct current generator 102 sends is fed back on the bus that two direct current generators connect jointly, works in order to drive the first direct current generator 101.
The electric current of tested motor, tachometer value are all adjusted to its ratings, just can carry out temperature rise test.This experimental provision in the ideal case, the electric energy that second direct current generator 102 sends is equal with the electric energy that the first direct current generator 101 consumes, but in reality, can be lossy in direct current generator operational process, need during temperature rise test to compensate this part loss, in the DC electric machine temperature test apparatus shown in Fig. 1, power compensation is completed by line power 104 or booster.
DC electric machine temperature test apparatus of the prior art, when carrying out temperature rise test to direct current generator, needs one with the direct current generator of tested direct current generator match specifications as accompanying motor.But, when carrying out temperature rise test to the large-size machine of small serial production, being difficult to suitable motor as accompanying motor, causing motor temperature-raising experiment to realize more difficult.
Shown in Figure 5, be electric machine temperature rise Experimental equipment in another kind of prior art.
In the apparatus, rectifier 203, PWM chopper 204 and wave filter 202 are sequentially connected in series between ac power input end and tested motor, and described DC filter capacitors 201 is connected between the output terminal of described rectifier 203, described control module 205 is by sine-wave generator 6, triangular-wave generator 207, first superimposer 208, second superimposer 209 and pwm signal generator 210 are formed, two input ends of described sine-wave generator 206 are connected with amplitude input end with frequency input respectively, the output terminal of this sine-wave generator 206 is connected with two input ends of the first superimposer 208 with direct current average voltage set-point input end, the output terminal of the first superimposer 208 is connected with the modulation signal input end of the second superimposer 209, the carrier input of the second superimposer 209 is connected with the triangular wave output terminal of triangular-wave generator 207, the output terminal of the second superimposer 209 is connected with the input end of pwm signal generator 210, and the gating pulse output terminal of this pwm signal generator 210 is corresponding with the Pulse Width Control input end of PWM chopper 204 to be connected.But this apparatus structure is complicated, and cost is high.

Embodiment:
In Fig. 1, motor 3 is connected with observing and controlling machine 1 by mechanical connecting device 2, and is electrically connected with controller 4 simultaneously.Motor 3 is three phase alternating current motor, and it operates under the control of controller 4.Measuring system 5 is arranged in the three-phase circuit between motor 3 and controller 4, and measuring system 5 is connected with any quarter-phase circuit of this three-phase circuit.Measuring system 5 is connected with PC 7 by signal regulating device 6.Measuring system 5 is powered by independently power supply, and to stop and the correlation behavior parameter of operating condition is measured motor, meanwhile, measurement result be sent in PC 7, PC 7 carries out the measurements and calculations of the internal resistance of motor winding and temperature rise automatically.
In order to measure the temperature rise of motor more accurately, usually the resistance variations by measuring motor winding calculates electric machine temperature rise, namely after motor has run certain operating mode, motor is shut down, thus resistance is tested, namely motor cooling procedure is tested.That is, in order to realize the calculating of electric machine temperature rise, be the test to motor cooling procedure to the test of electric motor resistance value.Relation between electric machine temperature rise and motor winding resistance value is shown below:
